Disparities and trends in the participation of minorities, women, and the elderly in breast, colorectal, lung, and prostate cancer clinical trials.

BACKGROUND: This study was done to determine the representation of minorities, women, and the elderly in National Cancer Institute (NCI) clinical trials. METHODS: This is an analysis in the NCI Clinical Data Update System. Patients were evaluated in breast, colorectal, lung, and prostate cancer trials from 2000 to 2019. Representation in a trial was determined by race/ethnicity, sex, and age. Secondarily, the change in trial participation by multivariable analysis by comparing years 2000 through 2004 to 2015 through 2019 was evaluated. RESULTS: The cohort included 242,720 participants: 197,320 Non-Hispanic White (81.3%), 21,190 Black (8.7%), 11,587 Hispanic (4.8%), and 6880 Asian/Pacific Islander (2.8%). Black and Hispanic patients were underrepresented for colorectal (odds ratio [OR], 0.58; 95% confidence interval [CI], 0.50-0.67; P < .001 and OR, 0.74; 95% CI, 0.64-0.87; P < .001, respectively), lung (OR, 0.83; 95% CI, 0.76-0.91; P < .001 and 0.66; 95% CI, 0.57-0.77; P < .001, respectively), and prostate cancer trials (OR, 0.85; 95% CI, 0.79-0.92; P < .001 and OR, 0.58; 95% CI, 0.51-0.66; P < .001) between 2015 and 2019. The odds of participation in 2015 to 2019 increased among Black patients in breast (OR, 2.19; 95% CI, 2.07-%2.32; P < .001), lung (OR, 1.54; 95% CI, 1.38-1.73; P < .001), and prostate cancer trials (OR, 1.14; 95% CI, 1.04-1.26; P < .001). The odds of participation in a trial among Hispanic patients increased for breast (OR, 3.32; 95% CI, 3.09-3.56; P < .001), colorectal (OR, 2.46; 95% CI, 2.04-2.96; P < .001), lung (OR, 3.88; 95% CI, 3.20-4.69; P < .001), and prostate cancer (OR, 1.70; 95% CI, 1.42-2.04; P = .005). CONCLUSIONS: This study identified that Black and Hispanic patients remain underrepresented in trials, but in recent years, participation has increased. These findings indicate that minority participation has increased over time, but further efforts are needed.

Metastasis and Mortality in Men With Low- and Intermediate-Risk Prostate Cancer on Active Surveillance.

BACKGROUND: Active surveillance (AS) is a safe treatment option for men with low-risk, localized prostate cancer. However, the safety of AS for patients with intermediate-risk prostate cancer remains unclear. PATIENTS AND METHODS: We identified men with NCCN-classified low-risk and favorable and unfavorable intermediate-risk prostate cancer diagnosed between 2001 and 2015 and initially managed with AS in the Veterans Health Administration. We analyzed progression to definitive treatment, metastasis, prostate cancer-specific mortality (PCSM), and all-cause mortality using cumulative incidences and multivariable competing-risks regression. RESULTS: The cohort included 9,733 men, of whom 1,007 (10.3%) had intermediate-risk disease (773 [76.8%] favorable, 234 [23.2%] unfavorable), followed for a median of 7.6 years. The 10-year cumulative incidence of metastasis was significantly higher for patients with favorable (9.6%; 95% CI, 7.1%-12.5%; P<.001) and unfavorable intermediate-risk disease (19.2%; 95% CI, 13.4%-25.9%; P<.001) than for those with low-risk disease (1.5%; 95% CI, 1.2%-1.9%). The 10-year cumulative incidence of PCSM was also significantly higher for patients with favorable (3.7%; 95% CI, 2.3%-5.7%; P<.001) and unfavorable intermediate-risk disease (11.8%; 95% CI, 6.8%-18.4%; P<.001) than for those with low-risk disease (1.1%; 95% CI, 0.8%-1.4%). In multivariable competing-risks regression, favorable and unfavorable intermediate-risk patients had significantly increased risks of metastasis and PCSM compared with low-risk patients (all P<.001). CONCLUSIONS: Compared with low-risk patients, those with favorable and unfavorable intermediate-risk prostate cancer managed with AS are at increased risk of metastasis and PCSM. AS may be an appropriate option for carefully selected patients with favorable intermediate-risk prostate cancer, though identification of appropriate candidates and AS protocols should be tested in future prospective studies.

Cell adhesion: integrating cytoskeletal dynamics and cellular tension.

Cell migration affects all morphogenetic processes and contributes to numerous diseases, including cancer and cardiovascular disease. For most cells in most environments, movement begins with protrusion of the cell membrane followed by the formation of new adhesions at the cell front that link the actin cytoskeleton to the substratum, generation of traction forces that move the cell forwards and disassembly of adhesions at the cell rear. Adhesion formation and disassembly drive the migration cycle by activating Rho GTPases, which in turn regulate actin polymerization and myosin II activity, and therefore adhesion dynamics.

Active surveillance for intermediate-risk prostate cancer in African American and non-Hispanic White men.

BACKGROUND: The safety of active surveillance (AS) for African American men compared with non-Hispanic White (White) men with intermediate-risk prostate cancer is unclear. METHODS: The authors identified patients with modified National Comprehensive Cancer Network favorable ("low-intermediate") and unfavorable ("high-intermediate") intermediate-risk prostate cancer diagnosed between 2001 and 2015 and initially managed with AS in the Veterans Health Administration database. They analyzed definitive treatment, disease progression, metastases, prostate cancer-specific mortality (PCSM), and all-cause mortality by using cumulative incidences and multivariable competing-risks (disease progression, metastasis, and PCSM) or Cox (all-cause mortality) regression. RESULTS: The cohort included 1007 men (African Americans, 330 [32.8%]; Whites, 677 [67.2%]) followed for a median of 7.7 years; 773 (76.8%) had low-intermediate-risk disease, and 234 (23.2%) had high-intermediate-risk disease. The 10-year cumulative incidences of definitive treatment were not significantly different (African Americans, 83.5%; 95% confidence interval [CI], 78.5%-88.7%; Whites, 80.6%; 95% CI, 76.6%-84.4%; P = .17). Among those with low-intermediate-risk disease, there were no significant differences in the 10-year cumulative incidences of disease progression (African Americans, 46.8%; 95% CI, 40.0%-53.3%; Whites, 46.9%; 95% CI, 42.1%-51.5%; P = .91), metastasis (African Americans, 7.1%; 95% CI, 3.7%-11.8%; Whites, 10.8%; 95% CI, 7.6%-14.6%; P = .17), or PCSM (African Americans, 3.8%; 95% CI, 1.6%-7.5%; Whites, 3.8%; 95% CI, 2.0%-6.3%; P = .69). In a multivariable regression including the entire cohort, African American race was not associated with increased risks of definitive treatment, disease progression, metastasis, PCSM, or all-cause mortality (all P > .30). CONCLUSIONS: Outcomes in the Veterans Affairs Health System were similar for African American and White men treated for low-intermediate-risk prostate cancer with AS.

Baseline Testosterone Levels in Men with Clinically Localized High-Risk Prostate Cancer Treated with Radical Prostatectomy with or without Neoadjuvant Chemohormonal Therapy (Alliance).

PURPOSE: Men with low serum testosterone at the time of prostate cancer diagnosis are frequently considered to have more aggressive disease. We examined treatment outcomes in men with clinically localized high-risk cancer to determine if baseline testosterone level identified men at higher risk for cancer progression after treatment. MATERIALS AND METHODS: Alliance/CALGB 90203 randomized men with clinically localized high-risk prostate cancer to radical prostatectomy alone or neoadjuvant chemohormonal therapy and radical prostatectomy. Men with available baseline testosterone levels who had not received androgen deprivation prior to study enrollment were studied (656). Testosterone level was examined as a continuous variable, as quartiles, and separately in men with an absolute testosterone level above/below 150 ng/dl. Outcomes evaluated were overall survival and event-free survival with events defined by biochemical recurrence, secondary treatment, prostate cancer metastasis, and death. RESULTS: We were unable to demonstrate a difference between baseline serum testosterone level measured as a continuous variable, as quartiles, or as a dichotomous variable (above/below 150 ng/dl) with the outcomes measured. This finding was observed in both arms of the study. CONCLUSIONS: Baseline serum testosterone level did not predict outcomes in men with clinically localized high-risk prostate cancer treated with radical prostatectomy alone or neoadjuvant chemohormonal therapy and radical prostatectomy.

Management of Lower Urinary Tract Symptoms Attributed to Benign Prostatic Hyperplasia: AUA GUIDELINE PART II-Surgical Evaluation and Treatment.

PURPOSE: Surgical therapies for symptomatic bladder outlet obstruction (BOO) due to benign prostatic hyperplasia (BPH) are many, and vary from minimally invasive office based to high-cost operative approaches. This Guideline presents effective evidence-based surgical management of male lower urinary tract symptoms secondary/attributed to BPH (LUTS/BPH). See accompanying algorithm for a detailed summary of procedures (figure[Figure: see text]). MATERIALS/METHODS: The Minnesota Evidence Review Team searched Ovid MEDLINE, Embase, Cochrane Library, and AHRQ databases to identify eligible studies published between January 2007 and September 2020, which includes the initial publication (2018) and amendments (2019, 2020). The Team also reviewed articles identified by Guideline Panel Members. When sufficient evidence existed, the body of evidence was assigned a strength rating of A (high), B (moderate), or C (low) for support of Strong, Moderate, or Conditional Recommendations. In the absence of sufficient evidence, information is provided as Clinical Principles and Expert Opinions (table[Table: see text]). RESULTS: Twenty-four guideline statements pertinent to pre-operative and surgical management were developed. Appropriate levels of evidence and supporting text were created to direct urologic providers towards suitable and safe operative interventions for individual patient characteristics. A re-treatment section was created to direct attention to longevity and outcomes with individual approaches to help guide patient counselling and therapeutic decisions. CONCLUSION: Pre-operative and surgical management of BPH requires attention to individual patient characteristics and procedural risk. Clinicians should adhere to recommendations and familiarize themselves with criteria that yields the highest likelihood of surgical success when choosing a particular approach for a particular patient.

Management of Lower Urinary Tract Symptoms Attributed to Benign Prostatic Hyperplasia: AUA GUIDELINE PART I-Initial Work-up and Medical Management.

PURPOSE: Benign prostatic hyperplasia (BPH) is a histologic diagnosis describing proliferation of smooth muscle and epithelial cells within the prostatic transition zone. The prevalence and severity of lower urinary tract symptoms (LUTS) in aging men are progressive and impact the health and welfare of society. This revised Guideline provides a useful reference on effective evidence-based management of male LUTS/BPH. See the accompanying algorithm for a summary of the procedures detailed in the Guideline (figures 1 and 2[Figure: see text][Figure: see text]). MATERIALS AND METHODS: The Minnesota Evidence Review Team searched Ovid MEDLINE, Embase, Cochrane Library, and AHRQ databases to identify eligible English language studies published between January 2008 and April 2019, then updated through December 2020. Search terms included Medical Subject Headings (MeSH) and keywords for pharmacological therapies, drug classes, and terms related to LUTS or BPH. When sufficient evidence existed, the body of evidence was assigned a strength rating of A (high), B (moderate), or C (low) for support of Strong, Moderate, or Conditional Recommendations. In the absence of sufficient evidence, information is provided as Clinical Principles and Expert Opinions (table 1[Table: see text]). RESULTS: Nineteen guideline statements pertinent to evaluation, work-up, and medical management were developed. Appropriate levels of evidence and supporting text were created to direct both primary care and urologic providers towards streamlined and suitable practices. CONCLUSIONS: The work up and medical management of BPH requires attention to individual patient characteristics, while also respecting common principles. Clinicians should adhere to recommendations and familiarize themselves with standards of BPH management.

Results of a Randomized Phase II Trial of Intense Androgen Deprivation Therapy prior to Radical Prostatectomy in Men with High-Risk Localized Prostate Cancer.

PURPOSE: This multicenter randomized phase 2 trial investigates the impact of intense androgen deprivation on radical prostatectomy pathologic response and radiographic and tissue biomarkers in localized prostate cancer (NCT02903368). MATERIALS AND METHODS: Eligible patients had a Gleason score ≥4+3=7, prostate specific antigen >20 ng/mL or T3 disease and lymph nodes <20 mm. In Part 1, patients were randomized 1:1 to apalutamide, abiraterone acetate, prednisone and leuprolide (AAPL) or abiraterone, prednisone, leuprolide (APL) for 6 cycles (1 cycle=28 days) followed by radical prostatectomy. Surgical specimens underwent central review. The primary end point was the rate of pathologic complete response or minimum residual disease (minimum residual disease, tumor ≤5 mm). Secondary end points included prostate specific antigen response, positive margin rate and safety. Magnetic resonance imaging and tissue biomarkers of pathologic outcomes were explored. RESULTS: The study enrolled 118 patients at 4 sites. Median age was 61 years and 94% of patients had high-risk disease. The combined pathologic complete response or minimum residual disease rate was 22% in the AAPL arm and 20% in the APL arm (difference: 1.5%; 1-sided 95% CI -11%, 14%; 1-sided p=0.4). No new safety signals were observed. There was low concordance and correlation between posttherapy magnetic resonance imaging assessed and pathologically assessed tumor volume. PTEN-loss, ERG positivity and presence of intraductal carcinoma were associated with extensive residual tumor. CONCLUSIONS: Intense neoadjuvant hormone therapy in high-risk prostate cancer resulted in favorable pathologic responses (tumor <5 mm) in 21% of patients. Pathologic responses were similar between treatment arms. Part 2 of this study will investigate the impact of adjuvant hormone therapy on biochemical recurrence.

Platelet and White Cell Reactivity to Top-Load Intravenous Perfluorocarbon Infusion in Healthy Sheep.

BACKGROUND: Perfluorocarbon emulsions (PFCs) are intravenous artificial oxygen carriers with enhanced gas solubility. As lipid micelle nanoparticle emulsions, PFCs may have a class effect that causes degrees of thrombocytopenia. Understanding the extent of the platelet effects, including mechanism and potential inflammation after PFC infusion, is important for safe human trials. METHODS: Normal sheep (Dorper) were infused with 5 mL/kg of Oxygent (w/v 60% PFC) or Perftoran (w/v 20% PFC). Controls received 6% Hetastarch or were naive. Blood samples were analyzed from baseline, time 0 (the end of infusion), 3 and 24 hours, and 4 and 7 days. Platelet count, plateletcrit, mean platelet volume, platelet distribution width, and CD-62p (a platelet activation-dependent membrane protein) were measured. Neutrophils, monocytes, and total white blood cell counts were analyzed. RESULTS: In these inflammatory cell lines, there were no consistent changes or cellular activation after PFC infusion. A decrease (<10% from baseline and naive controls) in platelet count was seen on day 4 after Oxygent infusion (3 g/kg), which recovered by day 7. No platelet effect was seen in Perftoran (1 g/kg). Plateletcrit, mean platelet volume, and platelet distribution width did not change significantly at any time point among the groups. CD-62p, ADP, and collagen aggregometry showed no significant change in platelet function. CONCLUSION: There was no evidence of overall reduction in platelet number, or any correlation with the change in platelet activation or inhibition. Therefore, the risk of increased thrombosis/bleeding after PFC intravenous infusion is low in this non-trauma sheep model.

Surgical Management of Lower Urinary Tract Symptoms Attributed to Benign Prostatic Hyperplasia: AUA Guideline Amendment 2020.

PURPOSE: The AUA Guideline panel provides evidence-based recommendations for the surgical management of male lower urinary tract symptoms (LUTS) secondary to benign prostatic hyperplasia (BPH). MATERIALS AND METHODS: The Panel amended the Guideline in 2020 to reflect additional literature published through September 2019. When sufficient evidence existed, the Panel assigned the body of evidence a strength rating of A (high), B (moderate), or C (low) for support of Strong, Moderate, or Conditional Recommendations. In the absence of sufficient evidence, the Panel provided additional information as Clinical Principles and Expert Opinions (See table 1[Table: see text]). RESULTS: Amendments to these Guidelines include: 1) an amended statement (Guideline 1) to include conducting a physical examination; 2) a new statement (Guideline 6) discussing concepts of treatment failure and retreatment; 3) an amended statement (Guideline 15) with updated supporting text for prostatic urethral lift (PUL); 4) an amended statement (Guideline 16) for PUL; 5) an amended statement (Guideline 17) with updated supporting text for transurethral microwave therapy (TUMT); 6) an amended statement (Guideline 18) with updated supporting text for water vapor thermal therapy; 7) updated supporting text for water vapor thermal therapy (Guideline 19); 8) an amended statement (Guideline 21) with updated supporting text for laser enucleation; 9) an amended statement (Guideline 22) with updated supporting text for Aquablation; and 10) an amended statement (Guideline 23) with updated supporting text for Prostate Artery Embolization (PAE). CONCLUSIONS: These evidence-based updates to the AUA Guidelines further inform the surgical management of LUTS/BPH.

Association Between African American Race and Clinical Outcomes in Men Treated for Low-Risk Prostate Cancer With Active Surveillance.

Importance: There is concern that African American men with low-risk prostate cancer may harbor more aggressive disease than non-Hispanic White men. Therefore, it is unclear whether active surveillance is a safe option for African American men. Objective: To compare clinical outcomes of African American and non-Hispanic White men with low-risk prostate cancer managed with active surveillance. Design, Setting, and Participants: Retrospective cohort study in the US Veterans Health Administration Health Care System of African American and non-Hispanic White men diagnosed with low-risk prostate cancer between January 1, 2001, and December 31, 2015, and managed with active surveillance. The date of final follow-up was March 31, 2020. Exposures: Active surveillance was defined as no definitive treatment within the first year of diagnosis and at least 1 additional surveillance biopsy. Main Outcomes and Measures: Progression to at least intermediate-risk, definitive treatment, metastasis, prostate cancer-specific mortality, and all-cause mortality. Results: The cohort included 8726 men, including 2280 African American men (26.1%) (median age, 63.2 years) and 6446 non-Hispanic White men (73.9%) (median age, 65.5 years), and the median follow-up was 7.6 years (interquartile range, 5.7-9.9; range, 0.2-19.2). Among African American men and non-Hispanic White men, respectively, the 10-year cumulative incidence of disease progression was 59.9% vs 48.3% (difference, 11.6% [95% CI, 9.2% to 13.9%); P < .001); of receipt of definitive treatment, 54.8% vs 41.4% (difference, 13.4% [95% CI, 11.0% to 15.7%]; P < .001); of metastasis, 1.5% vs 1.4% (difference, 0.1% [95% CI, -0.4% to 0.6%]; P = .49); of prostate cancer-specific mortality, 1.1% vs 1.0% (difference, 0.1% [95% CI, -0.4% to 0.6%]; P = .82); and of all-cause mortality, 22.4% vs 23.5% (difference, 1.1% [95% CI, -0.9% to 3.1%]; P = 0.09). Conclusions and Relevance: In this retrospective cohort study of men with low-risk prostate cancer followed up for a median of 7.6 years, African American men, compared with non-Hispanic White men, had a statistically significant increased 10-year cumulative incidence of disease progression and definitive treatment, but not metastasis or prostate cancer-specific mortality. Longer-term follow-up is needed to better assess the mortality risk.

Effect of a Behavioral Intervention to Increase Vegetable Consumption on Cancer Progression Among Men With Early-Stage Prostate Cancer: The MEAL Randomized Clinical Trial.

Importance: Guidelines endorsing vegetable-enriched diets to improve outcomes for prostate cancer survivors are based on expert opinion, preclinical studies, and observational data. Objective: To determine the effect of a behavioral intervention that increased vegetable intake on cancer progression in men with early-stage prostate cancer. Design, Setting, and Participants: The Men's Eating and Living (MEAL) Study (CALGB 70807 [Alliance]) was a randomized clinical trial conducted at 91 US urology and medical oncology clinics that enrolled 478 men aged 50 to 80 years with biopsy-proven prostate adenocarcinoma (International Society of Urological Pathology grade group = 1 in those <70 years and ≤2 in those ≥70 years), stage cT2a or less, and serum prostate-specific antigen (PSA) level less than 10 ng/mL. Enrollment occurred from January 2011 to August 2015; 24-month follow-up occurred from January 2013 to August 2017. Interventions: Patients were randomized to a counseling behavioral intervention by telephone promoting consumption of 7 or more daily vegetable servings (MEAL intervention; n = 237) or a control group, which received written information about diet and prostate cancer (n = 241). Main Outcomes and Measures: The primary outcome was time to progression; progression was defined as PSA level of 10 ng/mL or greater, PSA doubling time of less than 3 years, or upgrading (defined as increase in tumor volume or grade) on follow-up prostate biopsy. Results: Among 478 patients randomized (mean [SD] age, 64 [7] years; mean [SD] PSA level, 4.9 [2.1] ng/mL), 443 eligible patients (93%) were included in the primary analysis. There were 245 progression events (intervention: 124; control: 121). There were no significant differences in time to progression (unadjusted hazards ratio, 0.96 [95% CI, 0.75 to 1.24]; adjusted hazard ratio, 0.97 [95% CI, 0.76 to 1.25]). The 24-month Kaplan-Meier progression-free percentages were 43.5% [95% CI, 36.5% to 50.6%] and 41.4% [95% CI, 34.3% to 48.7%] for the intervention and control groups, respectively (difference, 2.1% [95% CI, -8.1% to 12.2%]). Conclusions and Relevance: Among men with early-stage prostate cancer managed with active surveillance, a behavioral intervention that increased vegetable consumption did not significantly reduce the risk of prostate cancer progression. The findings do not support use of this intervention to decrease prostate cancer progression in this population, although the study may have been underpowered to identify a clinically important difference. Trial Registration: ClinicalTrials.gov Identifier: NCT01238172.

Effects of Testosterone Treatment in Older Men.

BACKGROUND: Serum testosterone concentrations decrease as men age, but benefits of raising testosterone levels in older men have not been established. METHODS: We assigned 790 men 65 years of age or older with a serum testosterone concentration of less than 275 ng per deciliter and symptoms suggesting hypoandrogenism to receive either testosterone gel or placebo gel for 1 year. Each man participated in one or more of three trials--the Sexual Function Trial, the Physical Function Trial, and the Vitality Trial. The primary outcome of each of the individual trials was also evaluated in all participants. RESULTS: Testosterone treatment increased serum testosterone levels to the mid-normal range for men 19 to 40 years of age. The increase in testosterone levels was associated with significantly increased sexual activity, as assessed by the Psychosexual Daily Questionnaire (P<0.001), as well as significantly increased sexual desire and erectile function. The percentage of men who had an increase of at least 50 m in the 6-minute walking distance did not differ significantly between the two study groups in the Physical Function Trial but did differ significantly when men in all three trials were included (20.5% of men who received testosterone vs. 12.6% of men who received placebo, P=0.003). Testosterone had no significant benefit with respect to vitality, as assessed by the Functional Assessment of Chronic Illness Therapy-Fatigue scale, but men who received testosterone reported slightly better mood and lower severity of depressive symptoms than those who received placebo. The rates of adverse events were similar in the two groups. CONCLUSIONS: In symptomatic men 65 years of age or older, raising testosterone concentrations for 1 year from moderately low to the mid-normal range for men 19 to 40 years of age had a moderate benefit with respect to sexual function and some benefit with respect to mood and depressive symptoms but no benefit with respect to vitality or walking distance. The number of participants was too few to draw conclusions about the risks of testosterone treatment.

Surgical Management of Lower Urinary Tract Symptoms Attributed to Benign Prostatic Hyperplasia: AUA Guideline Amendment 2019.

PURPOSE: Male lower urinary tract symptoms (LUTS) secondary to benign prostatic hyperplasia (BPH) is common in men and can have negative effects on quality of life (QoL). It is the hope that this Guideline becomes a reference for effective evidence-based surgical management of LUTS/BPH. MATERIALS AND METHODS: The evidence team searched Ovid MEDLINE, the Cochrane Library, and the Agency for Healthcare Research and Quality database to identify studies indexed between January 2007-September 2017. Following initial publication, this guideline was amended in 2019 and reflects relevant literature published through January 2019. When sufficient evidence existed, the body of evidence was assigned a strength rating of A (high), B (moderate), or C (low) for support of Strong, Moderate, or Conditional Recommendations. In the absence of sufficient evidence, additional information is provided as Clinical Principles and Expert Opinions (table 1 in supplementary unabridged guideline, https://www.jurology.com). RESULTS: This Guideline provides evidence-based recommendations regarding management of LUTS/BPH utilizing surgery and minimally invasive surgical therapies (MIST). Additional statements are made regarding diagnostic and pre-operative tests. Clinical statements are made in comparison to what is generally accepted as the gold standard (i.e. transurethral resection of the prostate [TURP] monopolar and/or bipolar). This guideline is designed to be used in conjunction with the associated treatment algorithm (see figure).[Figure: see text]Conclusions:The prevalence and the severity of LUTS increases as men age and is an important diagnosis in the healthcare of patients and the welfare of society. This document will undergo updating as knowledge regarding treatments and future surgical options continues to expand.

A qualitative study exploring women's health behaviours after a pregnancy with gestational diabetes to inform the development of a diabetes prevention strategy.

AIM: To inform targeted interventions for women with gestational diabetes mellitus (GDM) by exploring the factors that influence their health behaviours and their preferences for lifestyle support. METHODS: Participants were women with previous GDM taken from a diverse inner-city UK population. Data collection involved focus groups (n = 35 women in six groups) and semi-structured interviews (n = 15 women). The transcribed data were analysed using framework analysis. RESULTS: Eight themes relating to factors influencing health behaviour were identified: psychological legacy of pregnancy, relationships with healthcare professionals, physical impacts of pregnancy, social support and cultural norms, life-scheduling, understanding and risk perception, appetite regulation, and prioritization of the baby. The women's recommendations for intervention components included addressing the emotional stress of pregnancy; conveying personalized risk in a motivational way, adopting a family-centered approach, focusing on women's health rather than just the infant's, and developing flexible interventions. These recommendations were used to construct a model integrating the behaviour-regulating factors with a suggested framework for intervention. CONCLUSIONS: This study identified some common drivers that may regulate the health behaviours of women following GDM, and recognized some ways to improve care to impact on this. Interventions for diabetes prevention in this population need to address factors at both the individual and systemic levels.

Germline testing in those at risk of prostate cancer.

Men with germline mutations in DNA repair genes are at an increased risk of prostate cancer. These germline mutations are commonly seen in conjunction with somatic DNA repair gene mutations in prostate tumors. This indicates that men with a personal or family history of prostate cancer-as well as other cancer syndromes arising from mutations in DNA repair genes-should be considered for genetic testing and counseling.

PURPOSE: Male lower urinary tract symptoms (LUTS) secondary to benign prostatic hyperplasia (BPH) is common in men and can have negative effects on quality of life (QoL). It is the hope that this Guideline becomes a reference on the effective evidence-based surgical management of LUTS/BPH. MATERIALS AND METHODS: The evidence team searched Ovid MEDLINE, the Cochrane Library, and the Agency for Healthcare Research and Quality (AHRQ) database to identify studies indexed between January 2007 and September 2017. When sufficient evidence existed, the body of evidence was assigned a strength rating of A (high), B (moderate), or C (low) for support of Strong, Moderate, or Conditional Recommendations. In the absence of sufficient evidence, additional information is provided as Clinical Principles and Expert Opinions (table 1 in supplementary unabridged guideline, http://jurology.com/). RESULTS: This Guideline provides updated, evidence-based recommendations regarding management of LUTS/BPH utilizing surgery and minimally invasive surgical therapies; additional statements are made regarding diagnostic and pre-operative tests. Clinical statements are made in comparison to what is generally accepted as the gold standard (i.e. transurethral resection of the prostate [TURP]-monopolar and/or bipolar). This guideline is designed to be used in conjunction with the associated treatment algorithm. CONCLUSIONS: The prevalence and the severity of LUTS increases as men age and is an important diagnosis in the healthcare of patients and the welfare of society. This document will undergo additional literature reviews and updating as the knowledge regarding current treatments and future surgical options continues to expand.

Systematic review of treatment intensification using novel agents for chemoradiotherapy in rectal cancer.

BACKGROUND: With the well established shift to neoadjuvant treatment for locally advanced rectal cancer, there is increasing focus on the use of radiosensitizers to improve the efficacy and tolerability of radiotherapy. There currently exist few randomized data exploring novel radiosensitizers to improve response and it is unclear what the clinical endpoints of such trials should be. METHODS: A qualitative systematic review was performed according to the PRISMA guidelines using preset search criteria across the PubMed, Cochrane and Scopus databases from 1990 to 2017. Additional results were generated from the reference lists of included papers. RESULTS: A total of 123 papers were identified, of which 37 were included; a further 60 articles were obtained from additional referencing to give a total of 97 articles. Neoadjuvant radiosensitization for locally advanced rectal cancer using fluoropyrimidine-based chemotherapy remains the standard of treatment. The oral derivative capecitabine has practical advantages over 5-fluorouracil, with equal efficacy, but the addition of a second chemotherapeutic agent has yet to show a consistent significant efficacy benefit in randomized clinical assessment. Preclinical and early-phase trials are progressing with promising novel agents, such as small molecular inhibitors and nanoparticles. CONCLUSION: Despite extensive research and promising preclinical studies, a definite further agent in addition to fluoropyrimidines that consistently improves response rate has yet to be found.

The comparative effectiveness of decision aids in diverse populations with early stage prostate cancer: a study protocol for a cluster-randomized controlled trial in the NCI Community Oncology Research Program (NCORP), Alliance A191402CD.

BACKGROUND: Treatments for localized prostate cancer present challenging tradeoffs in the face of uncertain treatment benefits. These options are best weighed in a process of shared decision-making with the patient's healthcare team. Minority men experience disparities in prostate cancer outcomes, possibly due in part to a lack of optimal communication during treatment selection. Decision aids facilitate shared decision-making, improve knowledge of treatment options, may increase satisfaction with treatment choice, and likely facilitate long-term quality of life. METHODS/DESIGN: This study will compare the effect of two evidence-based decision aids on patient knowledge and on quality of life measured one year after treatment, oversampling minority men. One decision aid will be administered prior to specialist consultation, preparing patients for a treatment discussion. The other decision aid will be administered within the consultation to facilitate transparent, preference-sensitive, and evidence-informed deliberations. The study will utilize a four-arm, block-randomized design to test whether each decision aid alone (Arms 1 and 2) or in combination (Arm 3) can improve patient knowledge and quality of life compared to usual care (Arm 4). The study, funded by the National Cancer Institute's Community Oncology Research Program (NCORP), will be deployed within select institutions that have demonstrated capacity to recruit minority populations into urologic oncology trials. DISCUSSION: Upon completion of the trial, we will have 1) tested the effectiveness of two evidence-based decision aids in enhancing patients' knowledge of options for prostate cancer therapy and 2) estimated whether decision aids may improve patient quality of life one year after initial treatment choice.

Men's Eating and Living (MEAL) study (CALGB 70807 [Alliance]): recruitment feasibility and baseline demographics of a randomized trial of diet in men on active surveillance for prostate cancer.

OBJECTIVE: To assess the feasibility of performing national, randomized trials of dietary interventions for localized prostate cancer. METHODS: The Men's Eating and Living (MEAL) study (CALGB 70807 [Alliance]) is a phase III clinical trial testing the efficacy of a high-vegetable diet to prevent progression in patients with prostate cancer on active surveillance (AS). Participants were randomized to a validated diet counselling intervention or to a control condition. Chi-squared and Kruskal-Wallis analyses were used to assess between-group differences at baseline. RESULTS: Between 2011 and 2015, 478 (103%) of a targeted 464 patients were randomized at 91 study sites. At baseline, the mean (sd) age was 64 (6) years and mean (sd) PSA concentration was 4.9 (2.1) ng/mL. Fifty-six (12%) participants were African-American, 17 (4%) were Hispanic/Latino, and 16 (3%) were Asian-American. There were no significant between-group differences for age (P = 0.98), race/ethnicity (P = 0.52), geographic region (P = 0.60), time since prostate cancer diagnosis (P = 0.85), PSA concentration (P = 0.96), clinical stage (T1c or T2a; P = 0.27), or Gleason sum (Gleason 6 or 3+4 = 7; P = 0.76). In a pre-planned analysis, the baseline prostate biopsy samples of the first 50 participants underwent central pathology review to confirm eligibility, with an expectation that <10% would become ineligible. One of 50 participants (2%) became ineligible. CONCLUSION: The MEAL study shows the feasibility of implementing national, multi-institutional phase III clinical trials of diet for prostate cancer and of testing interventions to prevent disease progression in AS.
